Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT32 (1967)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Eltanin expedition ELT32 conducted in 1967 (Chief Scientist: Dr. Kendall N. Moulton). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection.本数据集借助船载重力仪（Gravimeter）、回声测深声呐（Echosounder Sonar）与磁力仪（Magnetometer），在1967年执行的埃尔塔宁号科考航次ELT32中采集所得，本次航次的首席科学家为肯德尔·N·莫尔顿博士。该数据集文件采用MGD77格式，涵盖重力场（Gravity Field）、磁场（Magnetic Field）及单波束测深（Singlebeam Bathymetry）数据，且均在数据采集完成后进行了处理。
